The authors regret that the legend for figure 4 was incorrect. The legend should read as follows: Fig. 4. Production of IL-2 (A) and IFN-γ (B) by splenocytes stimulated with Con-A after ICV microinjection of different doses of morphine. Data for IL-2 are expressed as half-maximum units (± S.E.M.) and data for IFN-γ are expressed as mean picograms per milliliter (± S.E.M.). 1996 by The American Society for Pharmacology and Experimental Therapeutics
